How does ETC charge?

ETC charging method: Through the on-board electronic tag installed on the vehicle's windshield, dedicated short-range communication is established with the microwave antenna in the ETC lane at the toll station, and background settlement processing is carried out using computer networking technology with the bank. Precautions for using ETC: The ETC transaction sensing area is 8 meters. When encountering a vehicle in front that has stopped, to prevent the ETC device of the front vehicle from malfunctioning or not having an ETC device at all, maintain a distance of more than 10 meters from the front vehicle to avoid automatic sensing and paying for the front vehicle. The recognition speed for ETC lane passage is 20km/h. If the speed is too fast, the vehicle device information cannot be read, which will also result in a failed charge. Unauthorized disassembly or movement of the OBU device, detachment or loosening of the ETC electronic tag, etc., will cause the electronic tag to fail. It can be sent to the bank where the ETC card was processed or the highway service office for testing. If the loosening or detachment is not man-made, it only needs to be reactivated. When using a debit card to bind with ETC, insufficient balance will also lead to a failed charge. Follow the guidance of on-site staff to go to the manual MTC lane and use cash or card for passage. Poor sensing due to the vehicle's windshield being too thick. Especially for vehicles that have had their windshields replaced after an accident or those with modified front windshields, extra attention is needed.
As a long-distance driver, I'd like to share some details about ETC tolling. The charges are calculated based on pre-set mileage rates for specific road sections. When passing through a toll station, the vehicle's onboard OBU device connects wirelessly to roadside equipment, automatically calculates the fee, and deducts it directly from the linked bank card or account. The entire process requires no stopping, making it convenient and efficient. I recommend opening this service at a bank and depositing some funds in advance to avoid penalties for insufficient balance. The benefits of ETC are obvious: time savings, reduced emissions, and discounted toll rates. However, long-term users should monitor account balances to prevent overspending that could disrupt travel. OBU installation is simple - most banks provide it for free, just mount it on the windshield. If you encounter signal issues or failed deductions, contact customer service promptly to avoid compromising driving safety.
